155 example, x86_64 machines would expand that to <filename
156 class="directory">/usr/x86_64-unknown-linux-gnu</filename>. Because this is
157 a custom system, this target-specific directory in <filename
158 class="directory">/usr</filename> is not required. <filename
159 class="directory">$(exec_prefix)/$(target_alias)</filename> would be
160 used if the system was used to cross-compile (for example, compiling a
161 package on an Intel machine that generates code that can be executed
162 on PowerPC machines).</para>
